    <p>I made a simple code:</p> <pre><code>-(void) detailButtonPressed:(Business *) theBiz { BGDetailBusinessViewController * DetailBusiness = [[BGDetailBusinessViewController alloc]init]; [self.navigationController SafelyPushController:DetailBusiness]; DetailBusiness.businessDetailed = theBiz; } </code></pre> <p>My expectation is the following. Once the code is over, then then DetailBusiness will lost it's reference. However, it is retained by self.navigationController.</p> <p>When I press the back button popping out DetailBusiness from the self.navigationController, I expect viewDidLoad to be called because the last reference to the object used to be referred by DetailBusiness is already gone.</p> <p>It's not called.</p> <p>Is it normal? Is something wrong? Did I cause memory leak?</p> <p>Update: dealloc method is called nevertheless so I doubt it causes memory leak</p> <pre><code>-(void)dealloc { while (false);//Just checking if I am called at all by putting breakpoint here } </code></pre> <p>It's kind of strange. Usually anything did is paired with will and via versa. If there is viewDidLoad there will be viewWillUnload. If there is viewWillLoad, there will be viewDidLoad. Now there seems to be imbalance, and I wonder if anyone can explain.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
